Stress fracture, left tibia, initial encounter for fracture

This code signifies a stress fracture affecting the left shin bone, specifically when the patient is receiving initial active treatment for the fracture. A stress fracture is a small crack in a bone, often caused by repetitive stress or overuse, rather than a single traumatic event.

Apply this code for patients presenting with a newly diagnosed stress fracture of the left tibia who are undergoing initial treatment, such as immobilization, rest, or surgical intervention. Documentation should clearly state "stress fracture," specify the left tibia, and indicate that this is the first encounter for active management of this particular fracture.

• Ensure documentation explicitly states "stress fracture" to differentiate from acute traumatic fractures.
• Verify laterality (left tibia) is clearly documented; separate codes exist for the right and unspecified tibia.
• The "A" seventh character indicates an initial encounter for active treatment; use subsequent characters for routine follow-up or healing phases.
